I'm using the Rainier copper-plated lead right now. Also ordered some FMJ.
Nothing "special" exactly about 1000fps. Just a nice round number.
Hodgdon lists 3.9gr with a 158gr HDY XTP, but they don't mention OAL.
It seems to cycle more smoothly w/1.55" OAL, and I was sort of hoping I could reduce the pressure a little by running them longer.
